Fabricating ZnO nanorod arrays with precisely controlled morphology, alignment, and density is highly desirable but rather challenging. On the other hand, understanding the parameters that affect their final morphology and the growth mechanisms is significant to integrate such patterned ZnO nanorod arrays in various applications. Therefore, ZnO nanorod arrays with different density and morphology were fabricated by electron beam lithography (EBL) combined with the hydrothermal methods in this work. The influences of prepatterned geometry and the growth parameters such as seed layer, the precursor concentration, and the growth time on their final morphology were investigated. Under the coactions of EBL and the subsequent hydrothermal growth, ZnO nanorod arrays with precisely controlled density, position and morphology were achieved. The growth mechanism was also discussed in detail for the ZnO nanorod arrays which confined by the aperture with different size.
SAG1 may be an excellent vaccine candidate against T gondii. The immune protection induced by SAG1 against T gondii may be regulated by both hormone- and cell-mediated immune response.
Graphene has excellent properties, such as excellent conductivity, more pores, stable chemical and structural properties, high specific surface area, so it is usually used in the battery fields. In order to further explore the capacitive properties of graphene, this experiment used
electrochemical stripping method, the electrochemical electrode was characterized by constant potential treatment methods, cyclic voltammetry curve, and constant current charging–discharging curve. The capacitive performance of modified graphene at different potentials was compared.
If a constant potential peeling treatment is performed, the interlayer spacing of graphene increases, and this time, the specific surface area is enlarged, and the electrical properties of the graphene electrode material are correspondingly improved. Cyclic voltammetry curve results show that
the graphene electrode exhibits better capacitance performance after being treated with a constant potential in neutral electrolyte. When treating with 3.1 V constant potential and voltage range of -1.1 V–1.1 V, capacitance can reach 327.273 F. The chronopotentiometry curve results show
that 3.1 V graphene electrode mass ratio capacitance can reach 218.182 F/g under voltage range of -0.3 V–0.3 V, meeting the energy storage requirements of the battery industry, and it is expected to become an ideal electrode material in the field of supercapacitors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
